Myntra.com — my account hacked

My myntra account was hacked, while checking my mails, i got to know an order had been delivered to bhopal to some rashid ahmad.

Someone else placed order from my account using my myntra credit balance. The fraud changed my password, contact info and i did not get one notification on my phone. As soon as i was able to log in somehow, i changed the password and mobile details again.
I did not get any notification on my mobile for the order placement as otp but i can get updates for the offers that i don't even need
I have placed return request that's all i can do which i know is not of any use. I have sent mail, no response yet. I complained on fb, no serious response. Finally got a call saying sorry can't do anything except advising me to report the incident which i already did. Pathetic security and i am highly disappointed.
